Kettenburg PC
Kettenburg PC is a 31 ′ 9 ″ / 9.7 m monohull sailboat designed by George Kettenburg Jr. and built by Kettenburg Boats between 1929 and 1959.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Also known as PACIFIC CLASS or PACIFIC COAST ONE-DESIGN. Originally commissioned by San Diego Y.C., USA.

This was followed by the KETTENBURG 40 of which nearly 40 were built over a period of 7 years, an impressive number for boats of this type during this period. In later years, the firm concentrated more on repairs and maintenance of yachts as well as custom projects. An emerging fiberglass technology came to dominated the market for new sailboats.
Paul Kettenburg had re-joined the Kettenburg Boat Works in 1943 after having left the company to go work for General Electric in the lean depression years and by 1949 Paul was convinced there was a place in the lineup for a sloop between the 42' PCC and the 32 ' PC hull for about 60% of the cost and water displacement.

In fact, George Kettenburg Jr. agreed to build the boat in trade for a piece of land on Point Loma, that the Kettenburg family still owns. She was sold to Mr. George Jessop (of the Jessop Jewelry family) at a later date. Eventually sold to Mr. Paul Hartley Sr. in 1946. Upon his death, his extended family continued to enjoy the yacht.

A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, "Multihulls for Cruising and Racing", International Marine, Camden, Maine, 1991, states that a BN of 1 is generally accepted as the dividing line between so-called slow and fast multihulls.
